Lyophilizer

Freeze-drying or lyophilization Freeze-drying, or lyophilization, is the process of freezing a material then sublimating any frozen liquid directly from solid to gas. The method is often used to preserve food and pharmaceuticals, as it allows products to be easily stored and transported without requiring constant refrigeration. Vacuum pumps are required for this process, and should be sized according to the freeze-dryer. If the pump’s flow rate is too high, then vapor will be pulled through the freeze-dryer’s condenser too quickly, reducing its efficiency. It is also important to clean the condenser after each run to prevent sublimation of frozen chemicals into the vacuum pump. Freeze-dryer applications require an ultimate vacuum of 10-1 to 10-3 mbar, which can be achieved with single- and two-stage rotary vane pumps or ChemStar Dry Lyophilizer

Turbomolecular pumps

Turbomolecular Vacuum Pumps For a consistent, reliable performance and zero maintenance, you can rely on Turbomolecular Pumps to deliver every time. Our first Turbomolecular Pumps were sold in 1993, we now have over 16,000 installations worldwide. 85% are operating on semiconductor process tools, where they demonstrate exceptional levels of performance and reliability. Turbomolecular Pumps are the first choice for applications demanding high up-time, hydrocarbon-free pumping, minimal maintenance and low vibration. The rotor is entirely suspended by magnetic bearings so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing contact when rotor is rotated and no requirement for consequent pump maintenance. Energy saving technologies have been incorporated into each design phase of the product development to ensure reduced power consumption and operation efficiency, with no compromise on quality or performance. Increased Productivity: Quicker Pump Down to Base Pressure Compact Size: Saves Space & Makes for Easy Installation Low Cost of Ownership: Low Power & Utilities Consumption Maintenance Free: Economic
